- Biosurfactants are
surface-active substances synthesised by living cells. They have the
properties of reducing surface tension, stabilising emulsions, promoting
foaming and are generally non-toxic and biodegradable.
- Biosurfactants
enhance the emulsification of hydrocarbons, have the potential to
solubilise hydrocarbon contaminants and increase their availability for
microbial degradation. Biosurfactant producing microorganisms may play
an important role in the accelerated bioremediation of hydrocarbon
contaminated sites.
- The water-soluble
derivatives with low degree of esterification represent novel anionic
polymeric biosurfactants exhibiting emulsifying ability for oil/water
type emulsions as well as good performance properties. Rhamnolipid
biosurfactants are alternatives to common surfactants such as
nonylphenol ethoxylate, which has come under scrutiny for its potential
environmental toxicity.
- Biosurfactants are
surface active substances derived from living organisms, mainly from
microorganisms. At present biosurfactants are readily bio- degradable
and can be produced from renewable and cheaper substrates, they might be
able to replace their chemically synthesized counter parts. Among the
heterogeneous group of biosurfactants, the rhamnose containing
glycolipids produced by Pseudomonas.
- Various types of
biosurfactant are synthesized by a number of microbes particularly
during their growth on water-immiscible substrates. A majority of
biosurfactants are produced by bacteria.
- Biosurfactant produced from
water insoluble substrates such as used oils reduced the surface tension
of water to below 29 dynes/cm. The biosurfactant was produced during the
growth phase. The produced biosurfactant increased the apparent
solubility of naphthalene from 32 to over 500 mg/L.
- Soil washing with
biosurfactants reduces soil cleaning time more than 3 times. 80 80-90 %
of washed out oil can be re reused used. Only complex soil cleaning
technologies can be used as effective, short short-term and
multipurpose. Soil polluted by high concentration of oil can not be
cleaned using biological soil cleaning methods.
- Biosurfactant
technology can be an effective and nondestructive method for
bioremediation of cadmium and lead contaminated soil.
- A technology for
production of biosurfactants with moisturizing properties equivalent to
those of natural ceramides is established using yeast cells and
vegetable oils. The developed technology reduces production costs to one
tenth of natural ceramide products.
- Most of the
biosurfactants are high molecular weight lipid complexes which are
normally produced under highly aerobic conditions. This is achievable in
their ex-situ production in aerated bioreactors. When their large scale
application in petroleum and soil is encountered, their in-situ
production would be advantageous.
- Flavobacterium sp.
Flavolipid represents an entirely new class of biosurfactants. Some
believes that this new class of biosurfactants will be of interest for
potential use in a wide variety of industrial and biotechnology
applications. At present, bioremediation enhanced processes, using
bio-surfactants, have relied on the direct introduction of
biosurfactants into the contaminated site.
- Biosurfactant producers
constituted between 10– 35 % of the aerobic heterotrophic bacterial
population. The majority of the Ft. Lupton and Tall Grass Prairie
samples had biosurfactant producing populations at approximately 1 %.
Tulsa Rose Garden soils have a higher percentage of biosurfactant
producers over the Ft. Lupton and Tall Grass Prairie soils. The fraction
of biosurfactant producers was three times the level in the RST soil
than in the Tulsa Rose Garden soil
- The U.S. Environmental
Protection Agency has considered rhamnolipid biosurfactant in light of
the relevant safety factors in the Food Quality Protection Act of 1996
and under the Federal Insecticide, Fungicide, and Rodenticide Act and
has not identified any dietary or non-dietary exposure issues that may
affect the U.S. population in general, including infants and
children.
- International Access
Corporation in association with the Center for International Science and
Technology Policy at the George Washington University has undertaken a
comprehensive analysis of three important fields within the U.S.
biotechnology industry:
tissue engineering, bio-related devices, and
advanced bio-processes.
- The enormous
diversity of biosurfactants makes them an interesting group of materials
for application in many areas such as agriculture, public health, food,
health care, waste utilization, and environmental pollution control such
as in degradation of hydrocarbons present in soil .
-
Technology for the
production of Biosurfactants is developed in India
- The detergent,
personal care and consumer product sectors utilize nearly 60% of all
surfactants and, apart from a few major industrial uses, these areas
will afford the main potential for the development of new, high tonnage
surfactants
